Until November 11, Pam had an average life. A devoted caregiver for a disabled Vietnam Veteran, she was also a busy mother of her five adult sons. They went places, did things—life was just going along.

November 11 changed all that. Pam’s youngest son, John Mangan, 23, was struck and killed by a 2000 or 2001 metallic dark blue Dodge Dakota pickup truck. John was at approximately 8700 W. Camelback Road in Glendale Arizona at 3:20 am. This is a picture of the memorial his family and friends have placed at the site:

But despite the crushing weight of his death, his family is channeling their grief into efforts to find the person who so callously took John’s life. They are working closely with the police to locate the truck that hit him. Pam, her friends and sons are blanketing the Phoenix/Glendale Arizona area with Silent Witness fliers asking for any information which might lead to the identity of person behind the wheel of that truck on that fateful night.

Their ray of hope? Any information related to this incident should be reported to Silent Witness, a non-profit organization which enables anyone to leave an anonymous tip about the crime and possibly receive an award up to $1,000.

How it works

When citizens provide tips, they are given a confidential number. They are then advised to contact Silent Witness within certain timeframes if they have more information or want to check the status of their tip. Anytime they call, they use their confidential number -- not their name.

Calls are received at the local Silent Witness tip line phone at 480-WITNESS (480-948-6377). This phone is a stand alone instrument which does not provide caller ID, and conversations are not recorded. Text and web tips are just as secure and anonymous because they are received using encryption technology.

Rewards are distributed in a private, anonymous manner to the callers through a third-party.

If you have any information regarding this case, CASE #2012-1523, please contact Silent Witness at W-I-T-N-E-S-S (480-948-6377), or toll-free at 1-800-T-I-P-S. You can also leave a tip at the Silent Witness website at silentwitness.org.

By guaranteeing a caller’s anonymity, Silent Witness allows the caller to give information in a positive atmosphere without the prospect of retribution. By offering cash rewards for information leading to indictment or arrests, the program encourages otherwise reluctant callers to provide information.

Silent Witness is a non-profit program created to give citizens the opportunity to assist law enforcement in solving crimes. Citizens remain completely anonymous and are paid cash rewards of up to $1,000 when the information they provide leads to an arrest or indictment. Established in 1979, Silent Witness works in partnership with the community, media and law enforcement, and is a member of both Crime Stoppers USA and Crime Stoppers International.

Victims like Pam and her family are the reason Silent Witness is so important; and the list of victims is endless. Without the information citizens provide, law enforcement might not be able to piece together all the evidence that ultimately leads to an arrest...and a victim's case being solved.
